llo a/ZZ whom it may concern:

Be it known that l, OLoE ROHLEN, a citizen of the United States,residing at Galesburg, in the county of Knox and State of Illinois, haveinvented certain new and useful Improvements in Vindow Screens, of whichthe following` is a specification.

My invention relates to a window-screen supported in a guide-frame whichcan be set in the Window-frame, the screen made in twoindependently-movable sections provided with a contact-strip fixed tothe guide-frame and arranged between the screens to exclude the passageof insects when the screens are raised or lowered; in screen-sectionsformed of Woven wire or other suitable material stretched betweensheetmetal frames of novel construction, and in a cord and latch appliedto the upper screen-section, which is operated to release the latch bypulling the cord in either direction to raise or lower thescreen-sections; and it consists of constructions and combinations, allas will herein-` after more fully appear.

In the accompanying drawings, Figure l is a front elevation ofmywindow-screen with the lower screen-section partly raised and with theupper screen-section partly lowered; Fig. 2, a vertical sectionalelevation in the line n; @c in Fig. l; Fig. 3, a sectional plan in theline y y of Fig. l 5 Fig. 4L, an enlarged side elevation in detail ofthe spring-catch and a cord for actuating it, shown by full lines inposition to engage with the locking-staples and by dotted lines inposition free from such engagement.

The screens A A are supported in a guideframe B, formed of grooved siderails B', secured together by a top cross-piece C and intermediatecross-pieces D D', arranged opposite each other outside of the screens,and by an intermediate contact-strip E, located between the screens,which latter serves to shut off or bar the passage of dust or insectsthrough the space necessarily formed by the sunken faces or panels ofthe screen-sections, as will hereinafter appear.

Two parallel guide channels or grooves b are formed upon the inner facesof the guiderails B to extend the entire length of the rails, into whichthe screen-sections are fitted to slide freely and independently of eachsections being placed at either the upper or lower ends of theguide-frame. The guidefralne is made to fit `snugly into the w'indowframe or casing, and the outer face of said frame is preferably held incontact with the inner face of the window-sash. lW'hen thus applied to awindow, the lower sash may be raised to admit air into the room, whilethe lower screen is closed to exclude insects, and the upper sash may beopened while the upper screen is closed for the sanne purposes. Inwhatever position the screens may be placed relatively to each other thecontact-strip E will completely close the space between the screens,which is ordinarily exposed because of the very considerable differencein thickness between the inner netting and the frame of the screen. Theedges of the ends of this strip are recessed, so that the sections A and`A can be brought closer together and allow the strip to project intothe space between the stiles of each section, and thus bring the wirepart of the `screen close to said strip E, which also overlaps the lowerrail of the upper screen and the upper rail of the lower screen.

The screen-frames are made of sheet metal folded to receive the edges ofthe wire-netting a and wire rods d', over or around which the edge ofthe wire-netting is first folded. The edges of the sheet-metal frame arethen turned down' to completely envelop the wire rods and folded. edgesof the netting and tightly compressed around them to form a tight jointor seam. The sheet-metal frame will project where it partly encirclesthe wire rod a', and thus form a flirting lengthwise of thescreen-frame, which will strengthen said frame. By means of thisconstruction the frame will not only be greatly strengthened to permitthe use of lighter material, but the frame will hold the wire netting orcloth in place without rivets or any additional fast-V ening.

The sheet-metal frame is preferably made of a single piece of metal d2to form the two sides and one of the cross-pieces, and the othercross-piece is made of strips of metal a3, placed upon opposite sides ofthe lower edge of the netting, and thin strips of wood a4 are grooved toreceive the edge of the wire and other and admit of either or both ofthe'said i IOO the strips a3 and are secured by rivets a5, which alsosecure the metal strips together7 and thus provide a neatly-finishedframe which is both light and strong and will not warp or becometwisted.

The upper screen-section is conveniently raised and lowered and fastenedin its raised position by the following-described means: A spring-latchF is secured by a screw-stud f to the upper cross-bar of the upperscreenframe A, and consists of a wire spring f', coiled around the shankof the stud and bent at its ends to form locking-spurs f2, and also toform correspondingloops f3, through which the strands g of a cord G arepassed to provide means both for attaching the cord to the screenfran1eand for drawing the spurs together to release them from locking-staplesg4, secured to the upper cross-piece C of the guide-frame. The cord G isseparated into strands g gtor a short distance of its length to passthrough the loops f3 of the latch, and will draw the ends of thespring-latch together by pulling the cord G from either direction. Thecord G passes through a staple g', secured to the under side of thecross-piece C ot' the guide-frame, and is located between the staplesg4. The locking-spurs f2 are thus drawn together and raised until theycome directly opposite the staples gf, when the screen-trarne A has beenlifted to itsv full height, at-which point the cord G is releasedsuficiently to allow the spring f to exert itself and force the spurs f2outwardly to engage with the staples g4, and thus support the sash inits raised I claim as myinvention and desire to secure by LettersPatentl. In awindow-screen, the combination of a guide-frame, the stripE, secured tothe guide- -frame and having its sides at each endrecessed, and the upper and lower sections having their stiles in saidrecesses, and the upper sill of the lower section and the lower sill fthe upper section overlapping the strip E, substantially as described,so that the netting ot' the sections will abut against the strip E, forthe purpose set forth.

2. In a window-screen, the combination of the frame having staples g andg4, a sliding frame having a stud,awire spring secured to said stud andhaving loops f3 and lockingspurs f2, and a cord passing through thestaple g and having a split or separated portion` which passes throughand is connected above and below the loops f3, substantially asdescribed.

In testimony whereof I aiix my signature in presence of two witnesses.

OLOF ROHLEN.
